The Oehlbach BTR Evolution 5.1 is a Bluetooth audio transmitter and receiver for home audio equipment. It can send sound from a connected source to a wireless audio device, or receive sound from a wireless device for playback through an audio system. Before connecting it, decide which way the sound needs to travel.<\/p>\n
The product name specifies BTR Evolution 5.1, but the store\u2019s description and package contents refer to BTR Evolution 5.0. Check the model marking on the specific unit before buying. The technical details below come from the store\u2019s description; their applicability to the 5.1 model has not been confirmed.<\/p>\n
Transmit mode<\/strong> sends audio from a source connected by cable to a Bluetooth audio device. Choose this direction when you want to hear a wired source through a wireless listening device. Receive mode<\/strong> works in the opposite direction: the adapter accepts wireless audio and passes it to connected audio equipment.<\/p>\n To choose the right mode, identify the source and the equipment that will play the sound. For example, if you want to play music from a phone through a stereo system, the phone is the source, so the adapter must receive its audio. Use the transmit\/receive switch to select the mode. Before pairing, set the direction and check that your audio equipment is using the input or output to which the adapter is connected.<\/p>\n The store\u2019s description lists optical Toslink and analog stereo RCA connections. Choose a cable to match the connections on your equipment: use the optical cable where the audio path has a suitable Toslink connection, or RCA for analog stereo connections. The connector type alone does not establish the direction of the signal. Check that you are using an audio output on the source and an audio input on the equipment that will play the sound. If that equipment has several connections, select the one you used in its settings.<\/p>\n Start by tracing the audio path: which device sends the signal, and which one plays it? Set the adapter\u2019s mode switch, connect the chosen cable and power supply, then follow the included instructions and your wireless device\u2019s menu to pair them. The store lists pairing with two devices, but does not say whether both can be used at the same time. If you use the adapter to receive audio on one occasion and transmit it on another, check the switch position and selected audio connection each time.<\/p>\n Place the adapter near the equipment it connects to by cable, with enough room for the connectors and convenient access to the mode switch. The store specifies a 10 m wireless range without giving the measurement conditions. Consider the distance to the paired device and test the connection where you will actually listen. If the connection drops out in the room, try moving the adapter or the wireless device.<\/p>\n In a stereo system, connect the adapter to a suitable audio connection on your amplifier or other equipment. When playing music from a phone, select the input used by the adapter on the stereo system. To send sound to a wireless listening device instead, first check that your audio source has a suitable output.<\/p>\n The same check matters in a home cinema system: inspect the inputs and outputs on the particular component you intend to use. The presence of an optical or RCA socket does not, by itself, tell you which way its signal travels. When watching video, check whether the sound and picture stay in sync in your system. No reliable latency measurement is provided for this model.<\/p>\n If your system has several audio components, decide in advance which one will connect to the adapter and which one will be used to select the audio source. This makes it easier to know where to change the input, volume or playback settings. Pairing with two devices does not, by itself, establish that their audio can be mixed or sent to two listening devices simultaneously.<\/p>\n The store\u2019s description specifies Bluetooth 5.0 with backward compatibility and aptX HD. Check the marking on the specific unit before attributing these details, or the figures below, to the BTR Evolution 5.1. The stated wireless range has no defined measurement conditions.<\/p>\n The package list names a BTR Evolution 5.0, a power supply, a 1 m USB charging cable, a 30 cm RCA-to-3.5 mm adapter, a 20 cm AUX cable, a 1 m optical cable and instructions. Because that list names the 5.0 model, check the contents of the 5.1 variant before ordering.<\/p>\n First identify the audio source and the device you want to listen through. If the source is connected by cable, select transmit mode; if the source is a wireless device, select receive mode. Then check that your equipment is using the connected audio input or output and that the wireless devices are paired.<\/p>\n Check the sockets on both devices and the direction of the audio signal. Toslink is for the corresponding optical connection; RCA is for the corresponding analog stereo connection. Connect an output on the audio source to an input on the receiving side.<\/p>\n The store says the adapter can pair with two devices, but simultaneous use has not been confirmed. If you need that function, check the instructions for the specific model.<\/p>\n To play audio from a wireless device through the stereo system, connect the adapter to a suitable audio input and select that input on the system. To send audio from a stereo source wirelessly, check that the source has a suitable audio output.<\/p>\n Yes, if you want to add Bluetooth audio transmission or reception. The connection method depends on the inputs and outputs of your particular home cinema equipment. With video content, check audio and picture synchronisation yourself, as no reliable latency measurement is provided.<\/p>\n","protected":false},"excerpt":{"rendered":" The Oehlbach BTR Evolution 5.1 is a Bluetooth audio transmitter and receiver for home audio equipment.
